Signal every 3 khz on FO 29 this morning
by jeffory broughton 07 Nov '16

07 Nov '16

I swear I read a post somewhere a few days ago where someone heard an un modulated carrier every 3 khz on FO 29. But I can not locate that post.I experienced that on FO 29 this morning along with very strong FM activity using the same uplink frequency as George WI9I in the Dominican Republic on 145.927. jeff broughton

Day/Night SNR above 1GHz??
by Scott 07 Nov '16

07 Nov '16

Hello everyone! With talk of some of the future amateur satellites using higher and higher frequencies, I can assure you that I for one am going to have a lot of questions about the world above 1GHz. Since I have been taking baby steps by monitoring L-Band with some success, a pattern has become so regular that I wonder if it will be applicable if/when I am ever equipped to work next generation AmSats in the GHz range. I have noticed (quite reliably) that the quality of my received signal easily doubles at night. One example would be the Outernet data stream from Inmarsat 4-F3. The SNR value reported by the Outernet software might be in the area of –6- during the day, but often jumps to –11- or –12- (or even higher) at night. Is this normal? Should I generally expect to have significantly better performance above 1GHz at night (at least in the case of ground-to-space contacts)? If so, of course that would be nice to know before trying to work nextgen satellites on those higher frequencies. Thanks! -Scott, K4KDR Montpelier, VA USA

Coax Assemblies for Arrow Antenna 437 X 14
by David Mennerich 06 Nov '16

06 Nov '16

Hello - does anyone know if there are coaxial cable assemblies commercially available for the Arrow 437 X 14 to make it circular polarization? It so, seems like a fairly inexpensive way to get a circularly polarized antenna for satellite work. I'm looking for smaller circularly polarized antennas that could be used in my portable LEO SSB satellite setup. http://www.arrowantennas.com/arrowii/437x14ii.html Thanks, Dave N2TEB

This is a 1.5U CubeSat with a 15 meter to 10 meter linear transponder. The #HFsat 21.4 to 29.42 MHz inverting transponder will have a bandwidth of 30 kHz. The satellite will also carry an APRS digipeater on 145.825 MHz. crossed 1/4 wave whips on VHF and also a 10 meter dipole. No launch has yet been identified. IARU Coordination: http://www.amsatuk.me.uk/iaru/formal_detail.php?serialnum=528 US Naval Academy page: http://aprs.org/hfsat.html [Thanks to IARU and US Naval Academy] --------------------------------------------------------------------- UBAKUSAT 3U Linear Transponder CubeSat Turkey’s 3U CubeSat UBAKUSAT carrying an amateur radio 145/435 MHz SSB/CW transponder is planned to be deployed from the ISS in 2017. The linear transponder is almost the same as that on the TURKSAT-3USAT which was launched on April 26, 2013. The satellite is being developed by Istanbul Technical University, Faculty of Aeronautics and Astronautics, Space Systems Design and Test Lab (SSDTL) along with TAMSAT, GUMUSH and ERTEK Ltd, with some support of the RF lab of ITU (RFL) and Ministry of Transportation, Communication and Maritime in collaboration with the Japanese Government. The primary mission of UBAKUSAT is to provide voice communications for amateur radio stations around the globe. Additionally the satellite will carry the TAMSAT Simplesat card which will send telemetry data, including the relative radiation data absorbed by the card, to ground stations. There is also a CW beacon. The estimated duration of the satellite mission is about 6 to 12 months before re-entry. The launch from Japan to the International Space Station is planned for late 2016 or early 2017 and deployment from the ISS will occur sometime later. IARU coordinated frequencies: • 437.225 MHz CW Beacon • 437.325 MHz Telemetry • SSB/CW transponder: – 145.940-145.990MHz – 435.200-435.250 MHz IARU satellite frequency coordination pages http://www.amsat.org.uk/iaru/ Turkish Amateur Satellite Technologies Organization (TAMSAT) http://tinyurl.com/TurkeyTAMSAT [ANS thanks AMSAT-UK for the above information] --------------------------------------------------------------------- NASA CubeSat Launch Opportunity NASA has opened the next round of its CubeSat Launch Initiative in an effort to engage the growing community of space enthusiasts who can contribute to NASA's space exploration goals. The CubeSat Launch Initiative gives students, teachers and faculty a chance to get hands-on flight hardware development experience in the process of designing, building and operating small research satellites. It also provides a low-cost pathway to space for research in the areas of science, exploration, technology development, education or operations consistent with NASA's Strategic Plan. Applicants must submit their proposals electronically by 4:30 p.m. EST, Nov. 22, 2016. NASA will choose the payloads by Feb. 17, 2017, but initial selection does not guarantee a launch opportunity. Certain selected experiments are slated to be flown as auxiliary payloads on agency rocket launches or to be deployed from the International Space Station beginning in 2017 and running through 2020. NASA does not fund the development of the small satellites, and this opportunity is open only to U.S. nonprofit organizations and U.S. accredited educational organizations. One goal of the CubeSat Launch Initiative is to extend the successes of space exploration to all 50 states by launching a small satellite from at least one participant in each state in the next five years. During this round, NASA is particularly focused on gaining participation in the District of Columbia, Puerto Rico and 18 states not previously selected for the CubeSat Launch Initiative. These states are Arkansas, Delaware, Georgia, Iowa, Kansas, Maine, Minnesota, Mississippi, Nebraska, Nevada, New Hampshire, North Carolina, Oklahoma, Oregon, South Carolina, South Dakota, Washington and Wyoming. CubeSats are in a class of research spacecraft called nanosatellites. The base CubeSat dimensions are about 4 inches by 4 inches by 4 inches (10 centimeters by 10 centimeters by 11 centimeters), which equals one "cube," or 1U. CubeSats supported by this launch effort include volumes of 1U, 2U, 3U and 6U. CubeSats of 1U, 2U and 3U size typically have a mass of about three pounds (1.33 kilograms) per 1U Cube. A 6U CubeSat typically has a mass of about 26.5 pounds (12 kilograms). The CubeSat's final mass depends on which deployment method is selected. To date, NASA has selected 119 CubeSat missions from 66 unique organizations. Of those missions, 46 have been launched into space with 29 more CubeSats scheduled to go in the next 12 months.

ARRL Teacher's Institute/STE(A)M
by Philip Jenkins 05 Nov '16

05 Nov '16

One of my high school classmates, Teresa, is a former middle school math and science teacher. Teresa has now transitioned to being a staff member of North Carolina State University's Science House. While STEM is not the main focus of her position, she still does a lot of hand-on experiences in STEM areas, some for students and some for educators, here in western NC. I made her aware last month of the ARRL Teacher's Institute. which she is placing into her November newsletter. (I included links to the institute on ARRL's website.) This newsletter reaches at least 1350 points of contact, mainly STEM educators, most of them in NC. I offered to be a point of contact if anyone was interested in learning more about the ARRL program, and especially AMSAT/ARISS, as I am an ARRL PIO (Public Information Officer). So I'm asking for videos, websites, (videos/reports of) demonstrations, etc, which are relevant for STEM educators, especially as it involves ham radio, AMSAT, and ARISS so that I can pass these various references along to folks who might have seen Teresa's newsletter. I haven't heard from anyone YET, but the month is still young. I'm hoping there will be a few nibbles for the ARRL Institute at least, as I stressed to Teresa that it is virtually cost-free for the participants. Thanks in advance! Philip N4HF (N4HF(a)AMSAT.ORG)

ISS Packet downlink IGates are now tracking again...
by Robert Bruninga 04 Nov '16

04 Nov '16

Looking at Steve's ARISS.NET downlink page, as of 1800 UTC, 4 Nov , the following ARISS IGates appear to now be tracking the new ISS packet downlink frequency of 437.550 (+/- Doppler) for almost 2 days now. DG2HSI-1 G7HCE-10 K0KOC-7 K8YSE-4 KD0KZE KC5ILO-12 JA0CAW-6 JR5YCG-10 ON4ISS-6 RK9UM VK6CO-6 VK6HV-1 YC3BVG ZL4JL-6 Prior to that, the feed was lost for 20 days since the VHF radio failure 3 weeks ago. We do need some IGates to remain on the 145.825 frequnecy so that we can maintain the downlink of PCSAT and PSAT. SO far, these IGates are still on 145.825 today as seen on pcsat.findu.com CU2ZG-1 DG2MJR-10 DL5MAM DM0AI-10 HS3SRS-1 HS0BBD JA0CAW-6 KJ6VCP-2 K9VD KD8THX-6 KD0KZE LA3QMA-6 LW4DEM-6 N0AN SQ5MJA VA5BNC-3 W9CMG-2 XE3N-4 YC3BVG ZL4JL-6 Bob, WB4aPR
